BougeRV Yuma 200W CIGS Thin-Film Flexible Solar Panel, The Most Flexible Solar Panel with Tape for Easy Installation

This fit perfectly on the roof of my 25 ft airstream and keeps the batteries well charged.

For those who don't want to drill holes in the roof of their RV, this is a very good option. There are four adhesive strips on the back and the backing strips come off easily without mess even in hot weather. The adhesive is some sort of roofing cement like Henry's or something. Once the panel is laid down, it is not coming up. The panels are very flexible and durable. You can walk on them with no problem. I installed four 200W panels and at high noon. I am getting a total of 670W. Decent. My only real gripe with these are the price. They are spendy. However, Bouge often has deals on these and if you are patient, you might be able to pick these up in the low four hundred range. For me, the BougeRV Yuma 200W CIGS Thin-Film Flexible Solar Panel were a solid winner.

Oh man I’m so happy with these. Purchased two 200-watt CIGS with tape. Got them at a screaming deal also, for around $440 each. I was so tired of lugging around a portable panel to keep our battery charged while RVing, but also was not into placing multiple holes in our roof. One hole, to run the wires, is enough for me. These have been installed on our roof (in parallel) for just over two weeks and they’re already impressing us. It’s only been parked in our driveway (in Southern California end of august), but it’s been a great test so far, as we’ve had all kinds of weather. 2 x 200-watt panels connected in parallel: HOT, sunny weather (95°+): averaging around 260 - 300 watts. RAINY/CLOUDY: Even in complete cloud cover or actual rain, we saw as high as 150 watts. COOLER (not cold), sunny weather (by SoCal standards - which is around 80°f or less): We are actually getting in excess of 400 watts (as high as 427) around noon. This keeps our batteries (200 Ah lithium) topped up almost everyday. It fell to around 90% on days when there was 2 days of consecutive cloud cover. Admittedly, we aren’t running any high power demand appliances, but am happy to know it’ll keep the fridge, lights, water pump, and water heater running almost indefinitely, if required. Install was incredibly easy and they ain’t budging with that tape.

Cigs are the only flexibke solar panel worth getting that lasts past a few years

Installed on top of my iKamper rooftop tent, the adhesive is rock solid and made installation super easy. the cabling is quality and well done. I've been very happy with the output - works great to keep my batteries charged and ready to go at all times.
